WordPress, in recent versions, have forces the display of WordPress as the generator in meta tags along with the version information in the header of your WordPress blogs - . Unlike previous versions there is not easy way to remove it. Unless WordPress is using that to provide support (which it doesn't), I don't see any good reason for providing that extra bit of help to hackers, do you? Here is a simple plugin which will remove the WordPress generator meta tag along with its version information.

Download Angsuman's WordPress Header Info Remover Plugin, rename the file to wp-header-remover.php, upload it to wp-content/plugins folder of your blog and activate it from Plugin Management screen. It requires zero configuration. It does one thing and does it well - remove the useless WordPress version information header from your WordPress blog.

Note: This is written in PHP, like any other WordPress plugin. You can use this simple plugin as an example to develop your own WordPress plugins.
